Hi guys just found this site. Just what I was looking for. I have a quick question. I have 92 f150 with 213,000 miles and am the original owner. I have replaced the sending unit on the thermostat housing but I think there is another that operates the gauge. Can any one point me in the right direction ( location ). The tem. gauge doesn't work. Thanks for any help.

 

yeah, the temp sender for the gauge is in the rear of the intake, the one in the front is for the ecm

 

On the small block V8 the sending unit is the single wire sensor near the base of the distributor in the intake manifold. On the I6 it's on the passenger side rear of the block below the head.
